Description
(1) technical field
The utility model relates to a kind of gas pipeline connection set, particularly relates to a kind of anti-dismounting connection set that is used between gas meter and the pipeline.
(2) background technique
Gas meter is the gauge table that metering user uses coal gas, rock gas, no matter is the domestic consumer, or enterprises and institutions, all regularly submits expense with the shown numeral of combustion table to air feed unit.Existing gas meter and the Placement of transmission and distribution pipeline be gas meter the turnover pipe joint by the interlocking nut be connected with an end of combustion gas bend pipe with seal ring, the other end of combustion gas bend pipe is connected with fuel gas pipeline.This kind Placement makes the user be easy to reequip privately indoor gas pipeline when decorating house, gas safe is caused a lot of hidden danger, the user who also has is in order to pay dues less, in use privately table is pulled down, connecting tube directly is installed or with two joint upside-down mountings, formal dress again when waiting to look into the gas meter personnel and regularly consulting, the normal metering and the charge of combustion gas have seriously been disturbed, the gas quantity that gas company is exported is far longer than the statistical magnitude of checking meter of their reality, for company has brought serious economy loss.
(3) summary of the invention
In order to overcome the technical problem that exists in the above-mentioned prior art, the utility model provides the anti-dismounting of a kind of gas meter connection set.
The technological scheme that adopts is:
The anti-dismounting of gas meter connection set comprises bridge piece and anti-disassembly mechanism.On the bridge piece one end outer wall screw thread is arranged, the other end is fixed with the O RunddichtringO.Its structure outline is described anti-disassembly mechanism, comprises interlocking nut, ratchet ring, only locks packing ring, stage clip and pipe collar.Ratchet ring is fixed on the bridge piece, is positioned at the rear of O RunddichtringO; The interlocking nut back end covers and offers a plurality of sour jujube grooves, and the interlocking nut is nested with on ratchet ring, and only locking has a plurality of ratchets on the packing ring, and ratchet is an overall structure with only locking packing ring.Only lock gasket sleeve and be located on the bridge piece, the ratchet of only locking on the packing ring passes a plurality of sour jujube grooves corresponding on the interlocking nut respectively, and the difference roof pressure is on ratchet corresponding on the ratchet ring.Stage clip is nested with on bridge piece, and its front end is replaced and only locked on the packing ring, and pipe collar is set on the stage clip, and its front end contacts with the interlocking nut, and the rear end is connected with the bridge piece solid welding.
Above-mentioned stage clip can substitute with elastic washer.
Vertically be provided with a plurality of grooves on the outer wall of above-mentioned interlocking nut.
Working principle
The utility model adopts ratch mechanism, front end at bridge piece is equiped with a ratchet ring, ratchet ring and bridge piece are structure as a whole, a plurality of above sour jujube grooves on the end cap of interlocking nut back end, have been offered, be provided with at the rear of interlocking nut and only lock packing ring, the ratchet of only locking the packing ring front end penetrates in the interlocking nut, and plugs together in the ratchet of ratchet ring rear end.When the interlocking nut when clockwise direction rotates, then interlocking nut drive ratchet circle rotates together, and when the counterrotating of interlocking nut was dismantled, the ratchet on the ratchet circle was blocked by the ratchet on the ratchet ring, the interlocking nut can not be rotated, so just reached the purpose of anti-dismounting.When the needs demolition diaphragm gas meter, owing to offer a plurality of grooves that reduce intensity on the outer wall of locking nut, when wrench was firmly enough big, the interlocking nut will get final product demolition diaphragm gas meter after the interlocking nut is destroyed along the fracture of groove place.The fluting of interlocking nut does not reduce the Security that normal mounting is used.Except that locking nut, other part is all excellent, and replaceable ruinate locking nut re-assemblies, and continues to use.
Compared with the prior art the utility model has increased anti-disassembling function, and the dismounting of gas meter can only be undertaken by the combustion gas professional workforce, and the general user can't reinstall gas meter voluntarily.So just can prevent user demolition diaphragm gas meter or the preceding gas pipeline of modified table privately effectively, eliminate potential safety hazard, stop the people and taken place, can significantly reduce the loss of gas company for usurping the combustion gas phenomenon with technological means.The utility model also has simplicity of design, reliable performance, easy for installation, low cost and other advantages.
